A is more than just a spreadsheet; it is an essential engineering control document that bridges the gap between hydraulic theory and real-world equipment selection. By automating friction loss calculations, standardizing static lift measurements, and integrating safety factors, an Excel-based tool ensures that the selected booster pump delivers the correct pressure and flow for the life of the system.
A booster pump calculation isn't just a sum. It’s a balance sheet of energy.
Even well-intentioned spreadsheets have errors. Watch out for these:
Your XLS should ultimately generate a (flow vs. required head) to compare against pump manufacturer curves. If your spreadsheet cannot do this, it is incomplete. booster pump head calculation xls
Note: For Imperial units (feet, GPM, inches), the formula constant changes to 4.67. Step 3: Account for Fittings (Equivalent Length Method)
To calculate the required head for a booster pump, several parameters must be considered:
Use a standard Hunter’s Curve or IPC chart to convert total FU to Gallons Per Minute (GPM). 3. Calculate Friction Head Loss A is more than just a spreadsheet; it
| Input | Value | Unit | | --- | --- | --- | | Flow rate (Q) | 0.01 | m^3/s | | Length of pipe (L) | 1000 | m | | Diameter of pipe (D) | 0.1 | m | | Elevation of suction point (Zs) | 10 | m | | Elevation of discharge point (Zd) | 20 | m | | Friction factor (f) | 0.02 | - | | Velocity of fluid (V) | 1.5 | m/s |
Total Dynamic Head is the total equivalent height that a fluid must be pumped, taking into account friction losses in the pipe. It determines the working pressure of the pump. The formula for is:
Several robust, pre-made Excel sheets are available for free, saving significant design time. It’s a balance sheet of energy
A residential building of 6 floors (ground +5). Booster pump to supply potable water to 20 apartments. Flow required = 10 m³/hr.
If flow > 2 m/s and check valve present, add a warning cell using Joukowsky formula: ΔP = ρ × a × ΔV . Alerts if > 5 bar.
A booster pump is a device designed to increase the pressure of a fluid within a system. When a liquid travels from Point A to Point B, it loses energy due to gravity and friction. The pump must add enough energy to the fluid to overcome these losses and deliver the required flow at the required pressure.
If building an Excel sheet from scratch sounds daunting, there is a wealth of pre-made templates available online. You can download and modify structured TDH calculators from trusted engineering repositories, such as the comprehensive templates offered on sites like Piping-tools.net .
